She married a dying prince and she won three babies.

It is not particularly difficult to find cows with cowpox, and one cow can be used to vaccinate countless people.

"Yes."

Out of seventy people, Yu Yuanzheng only left Chunlei and four others to accompany her to the border.

When Yu Yuanzheng arrived at the border, it was already fifteen days after Shangguan Ziqi sent the letter.

"Ma'am, I'm sorry. I've made you suffer."

When Shangguan Ziqi saw the dusty Yu Yuanzheng, he apologized with heartache.

"Alright, you and I are husband and wife, no need to say so much. Just ask the emperor for more rewards for me in the future."

Thinking of the house, Yu Yuanzheng was very satisfied.

Money can't buy it.

"Besides, I'm also from the Great Wei. Canglan is so vicious and wants to destroy my peaceful life. Can I agree?"

Yu Yuanzheng hated the Canglan people for their disregard for human life.

Even the common people were not spared.

This is a cruel move that will bring about lightning and thunder from heaven.

"Madam, you're right. I've isolated all those infected with smallpox, but we haven't been able to stop the spread. Half of the enemy prisoners have been infected, and over 3,000 of our soldiers have been infected. Deaths have already occurred in the prisoner camps. In the several cities we've recaptured, returning civilians have also been infected. Fortunately, the number of returning civilians is small, so the spread isn't too rapid."

Shangguan Ziqi briefly talked about what had happened in the past few days.

"I left in a hurry at that time. Did the emperor send any edict?" Yu Yuanzheng came empty-handed, and their speed was definitely not as fast as the imperial edict.

"The emperor has already sent a royal physician on the way and has organized people to deliver medicinal herbs. But I don't know whether the herbs they send are suitable for use." Shangguan Ziqi said truthfully.

"Okay. I'll make another list and ask our nearest pharmacy supplier to ship some over." In the face of national crisis, this is not the time to worry about so many things. Let's control the epidemic first.

The people on the front line are all soldiers. Canglan wants to wear out the soldiers on the border of Wei Dynasty and then take advantage of them.

At the same time, it also caused the Wei Dynasty to lose its composure.

Humph, do you think you can stop the Wei cavalry with this vicious plan? Wishful thinking, let's see how she will destroy their plan.

The two of them talked all the way into the main tent.

"Husband, find twenty men you trust, and the four men from Qingfeng. I will arrange for them to go get the cowpox immediately. There is no time to lose."

Yu Yuanzheng didn't even have time to rest.

"it is good."

Shangguan Ziqi immediately asked Qingfeng to arrange manpower.

Soon, twenty strong men gathered outside the main tent.

"Comrades, this young master has important matters to arrange for you. This must be done in secret and must not be discovered by the Canglan people."

Yu Yuanzheng then taught them how to identify cows with pox, how to extract juice, and how to preserve it.

If you are not sure, just follow Qingfeng and the other three.

All four of them had seen how Yu Yuanzheng operated.

Moreover, the four of them have been vaccinated and are unlikely to get smallpox.

After receiving the order, Qingfeng and his three companions led their men to the nearest mountain village to look for cattle.

When the enemy attacks, villagers in mountain villages generally do not flee, but hide in the mountains. Only those in the city or surrounding areas will escape.

After Yu Yuanzheng sent the people away and wrote a prescription, she finally relaxed her mind which had been tense for over ten days.

After relaxing like this, I felt so tired that I just wanted to fall into bed and sleep.

She had been traveling for so many days, riding a horse the whole time.

My legs are numb.

"Madam, you take a nap first. I'll wake you up after Qingfeng and the others bring the things back." Shangguan Ziqi picked her up with a distressed look and walked into the inner room of the main tent, where he usually rested.

During this period, in addition to making military deployments to prepare for the enemy's attack at any time, he also had to control the spread of smallpox in the army as much as possible.

The military deployment was fine, but he really couldn't fully control the smallpox.

The number of people infected is increasing every day.

He had already placed each tent as far apart as possible, but he still couldn't control it.

Yu Yuanzheng was so tired that she fell asleep as soon as she touched the bed.

When she fell asleep again, it was already the next morning, and she was woken up by hunger.

He wolfed down a large bowl of porridge and a pancake.

The food in the military camp can’t be very good, it’s just edible.

Yu Yuanzheng is not picky.

"Eat slowly, no one will snatch the food from you." Shangguan Ziqi advised gently.

Seeing her eat so fast, he felt even more distressed. He guessed that she hadn't had a proper meal during these days on the road.

"Okay, have any of Qingfeng and the others come back?" Yu Yuanzheng put down his chopsticks and started asking about the business.

"not yet."

We just set off yesterday afternoon, so it wasn't that fast.

"Report."

As soon as he finished speaking, the voice of the guards came from outside.

"Come in."

A soldier who had just been transferred outside the main tent came in.

"Report to the commander-in-chief, this was sent back by General Luo Xiao. He ran away again after being sent outside the camp."

It can be seen how hurried he was. He remembered Yu Yuanzheng's words very well and went back to get another batch immediately.

Shangguan Ziqi took it.

"As soon as any are sent back, send them in immediately."

"Yes, Marshal."

“My dear, please set up a man at the city gate to collect porcelain bottles.

Pick it up as soon as they come back and let them go again, that way it will be faster." Yu Yuanzheng suggested.

Now they are racing against time.

"Okay. I'll arrange it right away."

Shangguan Ziqi arranged several young generals with good martial arts skills to guard the city gate.

Later, when they learned that this thing was a miracle drug for curing smallpox, they went out several miles to meet the person. When they saw the person coming back, they took the thing and ran back quickly.

It also increases efficiency.

Received the first porcelain vase.

Immediately vaccinate those who are not infected.

Chunlei, Xiayu, Zhuiyun and Zhuyue also had a night's rest and felt full of energy.

"You four, first watch how I operate and how to control the amount. When more juice comes back later, you will have to take charge." Yu Yuanzheng planned to let the four of them become the main force.

It's simple, you can learn it just by looking at it.

It cannot be performed by non-military doctors.

"Yes, sir." The four responded at the same time.

In the military camp, Yu Yuanzheng continued to wear men's clothes.

Wearing a mask is also a way to prevent spies from Canglan Country.

If her portrait was drawn and sent to Canglan Country, she would be in danger.

Moreover, her appearance in the military camp as a miracle doctor greatly encouraged the soldiers.

With her around, every soldier is more confident of surviving.

Even if it was smallpox, they held out great hope.

She is famous in Wei and many people know her.

Shangguan Ziqi ordered someone to notify all generals above the rank of lieutenant general to come to the main tent.

He didn't say what he asked them to do.

Let everyone line up outside and wait to be called in one by one.

This was also Yu Yuanzheng's idea.

Don't tell them the reason, just get vaccinated silently.

She has done this many times and has become skilled in controlling the dosage. It will not have much impact on healthy people. At most, it will cause a low-grade fever, which people who don't care much about will not feel.

A small bottle was used up by more than 200 people.

Everyone found it very strange that he only made a small cut on their shoulder, then wiped the wound with a cotton swab and told them to go.

There was a deputy general who was very familiar with Shangguan Ziqi and asked privately what this was for.

Shangguan Ziqi only replied: "You will know later."

That unfathomable look made the deputy general look confused.

As more and more juice was sent back, Yu Yuanzheng opened several tents, one for each of Chunlei and the other three, and asked everyone to be vaccinated in batches.

This process lasted for half a month before all the soldiers who had not been infected with smallpox were dealt with.

The main reason is that the acne juice can't keep up.

During this half month, the number of soldiers contracting smallpox continued to increase every day, but later on, the number of new cases per day became smaller and smaller.
